Four channel data logger with pulse and two-state inputs

Data logger is designed to record from four binary inputs or from two pulse and two binary inputs.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via USB-C.

Datalogger inputs can be set up for four binary inputs or two binary inputs and two pulse counters.

In case of exceeded set limits alarms are indicated by LED, LCD and acoustically by built-in beeper.

The device includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
